Problem with rebuild Discourse at Docker

Support Self-hosting
1

Hello,

I’m forced with an update problem. When I try to update Discourse via admin/upgrade page I receive information about the old Docker image.

So I try to connect to the Discourse server and update by typing the commands git pull and then rebuilding the app. But now I received the below error:

...
success Cleared cache.
Done in 8.44s.

Caused by:
PG::SyntaxError: ERROR:  syntax error at or near "CASCADE"

I tried updating Discourse with commented plugins section. But It didn’t help.

Searching discourse abut sync_bookmarks_polymorphic_column_data this function I only find this change in Discourse code DEV: Drop bookmark trigger correctly (#15486)

Where I can find more information about what happened? Or how to try to rebuild Discourse without the above change?

Did you skip a PostgreSQL upgrade by forcing an old version of the database in your app.yml?

I’m afraid you will need to update to our supported version by following PostgreSQL 13 update

Hi Rafael,

Good question! How I can skip a PostgreSQL upgrade? Is there a list of attributes I can use in app.yml?

If you use a specific Postgresql template with a version number in it, this will skip the upgrade.

i.e. using

templates:
  - "templates/postgres.12.template.yml"

rather than

templates:
  - "templates/postgres.template.yml"

will pin the Postgres to version 12 instead of ‘latest’ which is currently PG 13.
